DIRECTIONAL VALVES

EP16-S35 Piloted Spool-Type Logic Element

DESCRIPTION

A spool-type, screw-in, cartridge-style, hydraulic directional element, with multi-

function potential when used with other directional, pressure, or flow control devices.

OPERATION

The EP16-S35 is a spring-biased blocking valve which will shift to allow full flow from

1 to 2 only when pressure at 1 exceeds the cumulative pressure of 3, plus the bias

spring pressure value.

EP16-S35 is a pilot-to-close directional valve.

With no pressure at 3, flow will be allowed from 1 to 2 once the bias spring force is

overcome with pressure at 1.

It requires a tall cap when specified with bias springs from 6,2 to 16,5 bar (90 to

240 psi). The 240 psi spring requires an extra tall cap. A manual override option is

also available for valves with bias springs from 6,2 to 16,5 bar (90-240 psi).

NOTE: Orifice discs should not be used with this valve.

FEATURES

• Multiple function/application potential.

• Low pressure drop.

• Industry common cavity.

• Manual override available with 90, 110, 160 and 240 psi bias springs.
